the descending` fines F F, and also withthedescending tlues l( K, and also with the ascending flue-s o o, which dues surround the feed cylinder, as shown in Figs. 1,'2, and 9, and has its outlet through vulve G, hereinafter described.

E, Figs. l, 2, and t), represent the feed-cyl inder, the base of which is held in position inpendently of the firebrick at bearings t' z', v formed upon the inner surface of the outer` casin g of the stove, as shown in Fig. 2.

ff, Fig. 1, are the inner end platesV of the upper section of the stove, Ithe upper parts ot' which are lipped or made so as to recede i n ward.

In Fig. l, q g are perforated plates for the admission of cold air. These plates are outside of the plutesfj', as" represented in the iigure ,1' ust referred to.

II H is a ring, of elliptical form, which caps the upper section of the stove, and rests upon the upper edges of platesffand g g.

L L, Figs. l and t), are two cold-air ilues at the ends of the stove, which, starting from immediately underneath the ring II, pass upward through the tlues o o, so that the products ot' combustion in passing upward completely surround them. vThus the air `is heated in ascending through the lues L L.

By connecting the pipes represented in Fig. l0, Sheet 2, with the upper ends of the iue's L L, warm. air can be conducted into apartments in the upper part ofthe building.

In Figs. 2, 3, and 4, Sheet 1, G represents a perforated value, which regulates'the opera# tion of the stove. The office of this valve is to divide and distribute `equally and continually the products of combustion, so that every part of the stove Acan be heated atthe same time, and so as to carry oli' into the Hue behind at all times during the operation of the stove gall accumulations of gas. Two very desirable objects are thus obtained, and they are not obtained in any other stove. I

In all slu'iply-cylindcrcoal-stoves where the products of combustion are carried down ward into the baseot the stove more' or less of the gases will escape through unavoidable openings into the room.

. A valve constructed upon theprinciple shown in Figs. 2, 3,and et will entirely overcoine the objection, and the-operation will be as follows: The products of combustion rise within the tiro-pot c to its top and pass out through the openings c e lthrough the rebrick lining` D and openings c c, formed by the lipped projections of the dre-pot, into dcscending-ilues FF, as shown in Fig. l. Passing thence downward through chambers K, they aredistrihured by means of partition plates a a through the base` ofthe stove, whence they pass off into-flue J behind. At the same time, and while the products ot' combustion are descending into and being distributed through the base of the stove A and escaping through lue J, as described, a portion of them, together with the gases, are pass; i-ng upward and -escaping slowly through the central opening in valveG into the common due J. Thus we havea descending draft and Vat the same time a gentle ascending draft, as indicated by the direction of the arrows in i Fig. 1. Cold air, after passing through the perforated walls g g, is drawn closely to the heated plates f f, and when vthe air is par- IL L, which are heated by the products of combustion passing around them while passing upward through theue O, and'thence, the airI being thus heated, it enters pipes,

l i I I i l l which may be connected with the top of the i. i stove leading into a room above, as described above.

,i The valve G, which I have representedin Fig. i 4, has central slotted openings through it, and a slide, which can be used to regulate'the size of.said openings according to the amount of upward draft required.

I do not limit my invention to the use of a I valve constructed like that represented in Fig. 3, nor like that shown in Fig. 4, as Aa I variety of forms may be employed to obtain,

the result herein set forth. p

ln regard to the ascending lues L L and the branch connection represented on a small scale in Fig. 10, I will state that when it is not desired to warm other apartments than that in which the stove is arranged these parts may be. dispensed with.

Having thus described my invention, what ters Patent, is

burner which is constructed with ascending stove, and descending'ues passing down junction with an appliance which `shall admit of the escape of 'gas from -the upper section as described. 2. The application of a perforated valve or damper, G, or its equivalent, to a base-burner having ascending and descending dues, substantially in the manner described.
